Airpot’s pneumatic damping products are specifically designed to provide unparalleled damping and energy dissipation accuracy by eliminating friction from the working elements. The materials used have built-in lubricity, high strength-to-weight ratio, excellent stability under temperature / humidity extremes, close coefficients of thermal expansion, and non-deteriorating performance due to age or non-use. The basic parts are a graphitized carbon piston, precision ground to millionths of an inch TIR inside an annealed, borosilicate glass cylinder with a precision fire-polished bore. READ MORE
The Airpot Dashpot and Airpot Snubber cover a wide range of applications in which accurate control of motion, force and impact is required. The devices accomplish this by using the piston to force ambient air through an adjustable orifice at a controlled rate to dissipate kinetic energy.
Airpot Dashpot
Airpot Snubber
They prevent damage and violent or inaccurate response caused by shock and vibration in sensitive equipment and components, reduce impact noise and wear, provide simple, low cost, adjustable speed control without external power, and allow non-electrical timing capability. Their most common uses are as a spring damping device for velocity control, a vibration damper for oscillating masses, a solenoid damper to reduce impact force and noise, and an end-of-stroke shock absorber.
Springs provide motive force to a mass at the expense of continuously increasing velocity. Airpot damping develops an opposing force to limit this velocity to…
Airpot offers reliable timing control for non-electrical systems and for electrical systems requiring non-electrical backup. Application Examples In a commercial sprinkler system a pull damping…
Dashpot damping is one of the simplest ways of eliminating vibration. The Airpot dashpot excels in providing a high ratio of damping-to-friction force. Application Examples…
Poppet and check valves can naturally resonate, causing unwanted noise, pressure/flow fluctuations, or wear. These problems can be eliminated by precise damping. Application Examples In…
Many instruments are susceptible to random pulses and surges, which can lead to harmful, over-range conditions. The Airpot is velocity sensitive and resists these surges,…
When controlled deceleration is required at the end of the stroke of your mechanism, the Airpot snubber configuration is particularly useful. It performs push damping…
When choosing an Airpot damper for accurate pneumatic control of force and motion here are the primary functional differences to consider:
DASHPOTS:
Connected throughout the stroke to the damped mass
One or two way damping (push and pull)
Easily customized
Primary functions are accurate force or velocity control, vibration damper and oscillation stabilizer.
SNUBBERS, (PNEUMATIC SHOCK ABSORBERS):
Not connected to the mass they are damping
Primary function is energy dissipation
Used in accurate end-of-stroke shock absorbtion applications
One way damping only, (damp in compression)
Low force return spring for self resetting
